APPLICATIO S I FOR ATIO
charge the battery until the internal timer reaches 3 hours
(as set by C TIMER ). During recharge cycles, the LTC4062
charges the battery until the internal timer reaches
1.5 hours. Figure 3 describes the operation of the LTC4062
charger when charge time termination is used.
Charge Current Termination
Connecting the TIMER pin to ground selects charge cur-
rent termination. With this method, the timer is disabled
and a resistor (R DET ) must be connected from the I DET pin
to ground. I DETECT is programmed using the same equa-

terminates when the charge current falls below I DETECT .

This condition is detected using an internal filtered com-
parator to monitor the I DET pin. When the I DET pin falls
below 100mV for longer than t TERM (typically 1.5ms),
charging is terminated.

The Charge Cycle Ends After 3 Hours
When charging, transient loads on the BAT pin can cause
the I DET pin to fall below 100mV for short periods of time
before the DC current has dropped below the I DETECT
